Over the last few years Proseal has
been at the forefront of heat sealing
developments, running a series of
award-winning Masterclasses that have
defined ‘Heat Sealing Best Practice’
and been adopted as a benchmark of
quality by major-multiples and blue-chip
organisations in the UK and overseas.
The new ProTest system has evolved
from Proseal’s pioneering heat sealing
developments as major food producers
and retailers alike look for Proseal to lead
the way in seal quality testing solutions.
